This invention pertains to spinning or roving frames with particular reference to theconstruction and arrangement of the drawing rolls thereof and their mountings.

An object of the invention is to provide, in a spinning or roving frame, an improvement in bearing mountings for the drawing rollsso as to not only eliminate many bearings heretofore employed but to properlyshield the bearings against dirt, lint or any other impurities. I

: Another object ofthe invention is to provide, in a spinningor roving frame,'an improvement. in aligning, weighting and lubricating the top draft rollsinroving, or spinning machines employed inthe processing of cotton, wool, rayon, nylon or other fibers. V

A-further object of the invention is to provide, in a spinning or roving frame, an improvement in arranging and constructing the roll bearings in such a manner that the lubricating medium thereof will not find its way to the rolls to thereby damage-or render useless the work or yarn.

A still further object of the invention is to provide, in a' spinning or roving frame, an improvement in the weight distribution on the top rolls thereof.

An added object of the invention is to provide, in a roving or spinning frame, an improvement. in adjustment of the top rolls.

, The above and many other objects will become apparent from the succeeding description considered with the disclosures of the accompanying drawings, wherein:

Figure 1 is a plan view of a portion of a roving cr spinning frame embodying a form of the present invention.

Referring now to the drawingsin detaiLwherein like reference characters indicate like parts, the numeral l-is employed, in a somewhat gen-' eral manner, to-designate a portion of a spinning orroving frame embodying 'a combination of components characteristic of the present invention; .As' will be clearlyunderstood, a'co'mplete" spinning or roving frame is made upofialigfied multiples of the portion" illustrated in the draw ings and accordingly only one section will be' hereinafter described "Forming a part o'f the spinning or roving frame'is a roll stand 2 which" is anchored to a suitable support 3 (indicated diagrammatically) by any desired means so long as the roll stand is made'fast to the support The roll stand carries a bottom set of rolls which for thesake of clarity is designated as a bottom back roll 4, a bottom intermediate roll 5 and a bottom frontroll 6. Further, it is to be noted that all'the bottom rolls are necked with certain necks I anchored or suitably journaled in bearings forming a part of the roll stand and all the bottomrolls are driven positively by a gearing mechanism located at one end of the frame as is customary in machines of this type. More specifically the-bottom "back and front rolls have their exposed surfaces fluted or grooved as at-8 so as to more firmly grip the staple to be handled as well as for the purpose of advancing the staple in the process of spinning or roving from the back roll to and beyond the front roll. The intermediate roll 5 has associated therewith a frame member 9 which has side walls Ill straddling or adjacent each individual knurled portion of the bottom intermediate roll and these side walls are journaled on or carried by the necked portions of the bottom intermediate roll. The related or two side walls of each frame member are joined adjacent their rear extremities by a ledge II which also functions as a guide or rest in directing the staple from the rear bottom roll to the intermediate bottom roll. Also more spe cifically the bottom intermediate roll is of the apron type in that a continuous or uninterrupted flexible or preferably a rubber or. rubber com; pound bottom apron, or belt I2 is sleeved. over the intermediate bottom roll. Joining the frame members at a location which may be considered in advance of the intermediate bottom roll or between the bottom intermediate and front rolls is a bottom bar 13 firmly secured to the side walls and threaded through the bottom belt or apron. Since the bottom intermediate roll is knurled between necks thereof and this roll is, as previously stated-positively driven,- the belt or apron is egssegaeo tweenthe' top front roll and any of the other rolls the cap screw may then be loosened and a proper manipulation or adjusted disposition of the top front roll may be effected. The carrier for the top back and intermediate rolls is combined in a single component shown in an abnormal position in Figure 4 and in normal position particularly in Figures 1 and 2 of the drawings. The top back and intermediate roll carrier has a central shank 4| arranged to fit between the spaced rails 35 and carries spaced hubs 42 and 43. The hub 42 is an open or C-shaped hub while the hub 43 is completely enclosed or circular in formation. In each of these hubs there is an open or C-shaped brass 44 of a porous bearing material to neat y accommodate the jour'-.- nal necks 14b and I5?) of the top back and intermediate rolls. These hubs are also of'a width to substantially space the distance between the end portions [4a and |5a and thus a lubricating medium will not be thrown upon the roll portions l4aor theaprons or belts. The upper end of the central shank has, upstanding therefrom, an abutment 45 with the abutment and central shank cored to form a canal for the reception of a wick-type material 46 with openings communicating between the canal and brasses 44. A deposit of oil or any desired lubricating medium in the canal will be therein reservoired and func- ,tion as a lubricating supply for the journal necks Nb and l5b.

In order to change the relationship between the top back and intermediate rolls and the top front roll the front roll carrier rails are joined by a barrier 41 intermediate the ends thereof and this barrier is provided with a threaded opening for the accommodation of a set screw 48, the free end of which abuts the abutment 45 .(see particularly Figures 1 and 2). A manipulation of the set screw will cause the top. back and intermediate roll carrier to be moved in a direction toward or away from the top front roll and thus the relationship between these rolls may be easily and quickly altered even while the machine is in operation.

As previously indicated the top rolls are adequately weighted so that a proper pressure may bemaintained on the staple. Toward the accomplishment of this feature there is provided a saddle or weight distributing bar d9 being somewhat arched as viewed in Figure 2 for the purpose of rigidity and strength. The front roll carrier hub 3| has upstanding therefrom a pin 50 formed integral therewith. The front end of the saddle or weight distributing bar has an aperture 5| to loosely accommodate the pin 50 and .thus theformer and top front roll carrier are interlocked or the weight distributing bar is maintained in a positive and fixed position relative to the top front roll carrier. The top rear and intermediate roll carrier has an anvilor weight distributing block 52 mounted on the central shank thereof through the medium of a screw 53 or any other tightening means. The weight distributing block is bifurcated as at 54 to accommodate the screw and thereby render it adjustable forwardly and rearwardly of the machine. Extending from a front extremity of the weight distributing block is a knife edge or fulcrum block 55 which functions as a bearing line or area for the rear extremity of the weight distributing bar. Since a load is to be applied to the weight distributing bar, as more fully explained hereinafter, it will be observed that if it is found in service that the load is not 6 properly distributed between the topback and intermediate rolls thescrew 53 may be turned back and the weight distributing block shifted either forwardly or rearwardly as desired and the screw tightened once more to hold the associated parts in a fixed relationship.

Applying a load to the weight distributing bar is accomplished through the medium of a stirrup 56 which is an elongated, plate-like member as clearly shown in elevation in Figure 7 of the drawings. The weight distributing bar has intermediate its ends, a shoulder 51 into which is screwed an adjustable member or weight distributing screw 58. The stirrup is provided with an opening or slot 59 at its upper ,end and the weight distributing bar is threaded through this opening so that-the stirrup can be hung on or interlocked with the adjustable member. If, during service it is found that the applied load isnot properly distributed between the forward end of the top front roll carrier and the combined top back and intermediate roll carrier, a manipulation of the adjustable member .58 will correct this situation.

The stirrupextends downwardly from the weight distributing screw through the machine between the intermediate and front rolls to terminate at a location adjacent the'support 2. In the proximity of the 'supportthere'is' provided an anchor bolt 60 having an eyelet head 6!. While any suitable weighting. means or mechanism may be employed the preferred arrangement for weighting all three top rolls is a lever 62 having suspended from one or arear end thereof a load or weight 63 only a part of which is illustrated. The front end of the lever is hook-shaped in configuration and thus it extends through a suitable opening 64 in the lower area of the stirrup and the eye 61 of the adjustable anchor bolt.

The present invention also contemplates or embraces a mechanism to protect the necked-portions 1 of the bottom rolls. 7 Toward the accomplishment of the latter and with particular reference to Figures 1, 5 and 6 of the drawings there is provided a shield or cover plate. 65 of hollow or skeletonized design. The cover plate is of somewhat tubular configuration and as such has properly arranged openings 66 in alignment with the bottom roll necked portions previously referred to. The shield or cover plate has a core of lubricating medium carrier or wick-type packing 61 which is arranged to extend through the openings 66 and bear upon the lower roll necked portions thereby maintaining these necked poran oil cup 68 properly capped and communicating with the core of the shield. Thus a reservoir or lubricant supply is arranged to saturate or load the wick-type packing and the oil cup is at the forward end of the shield and thus easily accessible. In order to keep the oil away from the rolls, the shield or cover plate has skirts 69 which overlap the roll stand between the various bottom rolls. Since the shield does not carry any loads from the bottom rolls a complex shield securing means is not believed necessary and accordingly a single set screw 10 is arranged to pierce the shield at its uppermost extremity and turn in a suitable screw hole H formed in the roll stand. As is customary in machines of this type a clearer T2 is arranged to bear upon the top front roll and as a support for the clearer the shield is utilized. Toward this end the cover plate has upstanding 7 thereirom a. yoke or.- clevis': typesextensiom (43 which ratherlooselyiaccommodates: a 13111 501: axle 14 o't'ithe clearer;
